I never imagined my wedding unless pressed by other girls. Then I would just dream up the coolest party I could think of, and I thought white dresses were dumb and boring. Then, as a teen, in a very conservative Christian school, I admitted that I didn't want to marry, ever. No shit, the girl in front of me gasped "but where will you LIVE????"
Yeah.
I also had no problems with no attachment sex all through college and young adulthood, so that should have been a clue, hah. But not having a term for what I was for most of my life, it definitely took a while to accept how i am, and some trauma.
